Canadian folklore if i remember correctly:
It is a malevolent cannibalistic spirit into which humans could transform, or which could possess humans. Those who indulged in cannibalism were at particular risk, and the legend appears to have reinforced this practice as a taboo.
Its a belief of the Algonquin native Americans, mostly on the Canadian side. If you ate another human than you would likely become one, the southern tribes believed that the wendigo was a spirit that would posses you at random if the wendigo ceremony was not done. the ceremony was used by all Algonquin native Americans though, usually to warn people not to cannibalize other tribesmen. The title of this chapter is likely a reference to the cannibalistic nature of zombies though, not that someone will eat another person, not while aforementioned person is alive anyways.
Dont long paragraphs make you feel accomplished and smart, or is it just me?
